INTERNAL-COMBUSTION SINGLE-ACTING- ENGINE CYLINDER.

Application filed December 14,1923. Serial No. 680,764.

To all whom it may concern:

Be it known that I, IsAAo' Coun'rrrwnrrn GREEN, a British subject, residing at 15 York Avenue, Jordan Hill, Glasgow, Scotland, have invented certain new and useful Improvements in lnternalrCombustion Single-Acting Engine Cylinders, of which the following is a specification.

This invention relates to internal combustion single-acting engine cylinders of the type which includes a separate casting for the cylinder liner, and has for its object to provide a special construction of liner, which enables the useful life of the latter to be prolonged.

It is found that the part of the cylinder liner surface which is nearest to the com bustion chamber is most subject to wear due to the abrasive action of the piston and piston rings. The other end of the cylinder liner, viz, the end remote from the combustion chamber, is subject to comparatively little wear.

The present invention consists essentially in constructing the cylinder liner so that it is reversible or symmetrical end for end, whereby when one end is worn the liner may be reversed end for end and used for a further period. In this way the useful life of the liner is approximately doubled.

The accompanying drawing illustrates one construction of my improved cylinder, the

drawing showing the cylinder in section.

With reference to the drawing, the cylinder cover or breech A is securedby means of bolts or screws B to the .liner C, which is symmetrical end for end, so that the flange E, which abuts the cylinder cover'A, is an exact duplicate of the flange F at the opposite end of the liner. The jacket I) may be in one piece or of two or more pieces connected by bolts G, or any other well known means. 7

l/Vhen the liner C has become badly worn by the abrasive action of the piston and rings at theend of the liner nearest flange E, then the liner is removedand replaced so that the position previously occupied by flange E is now occupied by flange F and ice-verse. The worn portion of the liner is then remote from the combustion chamber, whereas the comparatively unworn part of the liner is adjacent to the combustion chamber. In this way the useful life of the liner is practically doubled.

It will be understoodthat the particular construction illustrated in the drawing is by way of example onlyand that the invention covers any arrangement of a cylinder liner which is symmetrcial end for end and which may have a flange or be capable of being flanged at each end, whereby either end may be fixed to the cylinder cover or invention.

1 claim: 1. An improvement in motor cylinders for single acting combustion engines of that kind in which one endof the cylinder liner is connected with thecylinder cover so as to allow the liner to freely expand downwards,

comprising, a cylinder cover, and a cylinder liner, each end of the liner being provided with means for fastening the liner to the cover.

2. An improvement accordingto claim 1, r

the ends of saidcylinder liner being symmetrical.

3.,An improvement according to claim 1,

c said. means for fastening the liner to the cover, being fastening flanges.

l. An improvement according to claim 1., the ends of said cylinder liner being symmetrical, said means for fastening the liner to the cover, being fastening flanges.

An improved cylinder liner, each end of the. liner having fastening means for alternatively.connecting the liner to a cylinder cover, whereby the liner can be reyersed end for end relative to the cover, in

order to prolong its life.

6. An improved cylinder liner according to claim 5, said fastening means being symmetrical. V

7. An improved cylinder liner according to claim 5, said fastening means being connectin flanges.

In testimony whereof I affix my signature.
